Definitions

• the present invention relates to a process for producing particles of amine reaction product.
• perfumed products are well-known in the art. However, consumer acceptance of such perfumed products like laundry and cleaning products is determined not only by the performance achieved with these products but also by the aesthetics associated therewith. The perfume components are therefore an important aspect of the successful formulation of such commercial products.
• perfume additives make such compositions more aesthetically pleasing to the consumer, and in some cases the perfume imparts a pleasant fragrance to fabrics treated therewith.
• the amount of perfume carried-over from an aqueous laundry bath onto fabrics is often marginal and does not last long on the fabric.
• fragrance materials are often very costly and their inefficient use in laundry and cleaning compositions and ineffective delivery to fabrics results in a very high cost to both consumers and laundry and cleaning manufacturers. Industry, therefore, continues to seek with urgency for more efficient and effective fragrance delivery in laundry and cleaning products, especially for improvement in the provision of long-lasting fragrance to the fabrics.
• viscous it is meant a product which has a viscosity higher than 1000 cps.
• the viscosity is measured on a rheometer, TA Instrument CSL 2 100 at a temperature of 25C with a gap setting of 500 microns.
• salt carrier a carrier which forms a salt with the amine reaction product.
• the salt formation occurs by reacting the amine reaction product with an acid.
• the salt formation takes place via a reaction of the acid at the nitrogen of the ⁇ -aminoketone or imine function.
• the salt formation may also take place at other nucleophilic centers of the amine or amine reaction product. Indeed, it is believed that when the salt formation takes place at the nucleophilic center of the primary amine, the link nitrogen-active tends to be more labile and therefore may liberate the perfume in-situ.
• Typical examples of such other suitable nucleophilic centers are the tertiary and secondary amine functions in polyethylenimine polymers.
• the present invention is a process for making particles of amine reaction product of a compound containing a primary and/or secondary amine functional group and an active ketone or aldehyde containing component, and which comprises the steps of:
• the obtained amine reaction product is further processed to form a coated particle.
• the obtained particle or coated particle is incorporated in a finished composition.

• Odour Intensity Index it is meant that the pure chemicals were diluted at 1% in Dipropylene Glycol, odor-free solvent used in perfumery. This percentage is more representative of usage levels.
• Smelling strips, or so called “blotters” were dipped and presented to the expert panellist for evaluation. Expert panellists are assessors trained for at least six months in odor grading and whose gradings are checked for accuracy and reproducibility versus a reference on an on-going basis. For each amine compound, the panellist was presented two blotters: one reference (Me Anthranilate, unknown from the panellist) and the sample. The panellist was asked to rank both smelling strips on the 0-5 odor intensity scale, 0 being no odor detected, 5 being very strong odor present.

• preferred detergent compositions will incorporate one or more of surfactants, organic and inorganic builders, soil suspending and antiredeposition agents, suds suppressors, enzymes, fluorescent whitening agents, photoactivated bleaches, perfumes, colours, and mixtures thereof.
• composition of the invention may take a variety of physical form including liquid, gel, foam in either aqueous or non-aqueous form, granular and tablet forms.
• a packaged composition comprising the processed product of the invention or composition of the invention.
• the packaged composition is a closed packaging system having a moisture vapour transmission rate of less than 20g/m 2 /24 hours. Typical disclosure of such a package can be found in WO 98/40464.
• Still another preferred package is a spray dispenser.
• the present invention also relates to such compositions incorporated into a spray dispenser to create an article of manufacture that can facilitate treatment of fabric articles and/or surfaces with said compositions containing the amine reaction product and other ingredients (examples are cyclodextrins, polysaccharides, polymers, surfactant, perfume, softener) at a level that is effective, yet is not discernible when dried on the surfaces.
• the spray dispenser comprises manually activated and non-manual powered (operated) spray means and a container containing the treating composition. Typical disclosure of such spray dispenser can be found in WO 96/04940 page 19 line 21 to page 22 line 27.
• the articles of manufacture preferably are in association with instructions for use to ensure that the consumer applies sufficient ingredient of the composition to provide the desired benefit.
• compositions to be dispensed from a sprayer contain a level of amine reaction product of from about 0.01% to about 5%, preferably from about 0.05% to about 2%, more preferably from about 0.1% to about 1%, by weight of the usage composition.
• Also provided herein is a method for providing a delayed release of an active ketone or aldehyde which comprises the step of contacting the surface to be treated with a a compound or composition of the invention, and thereafter contacting the treated surface with a material, preferably an aqueous medium like moisture or any other means susceptible of releasing the active from the amine reaction product.
• surface it is meant any surface onto which the compound can deposit. Typical examples of such material are fabrics, hard surfaces such as dishware, floors, bathrooms, toilet, kitchen, paper, skin, and other surfaces in need of a delayed release of a perfume ketone and/or aldehyde such as that with litter like animal litter.
• the surface is selected from a fabric, a tile, a ceramic; more preferably is a fabric.
• delayed release is meant release of the active component (e.g perfume) over a longer period of time than by the use of the active (e.g., perfume) itself.
• ⁇ -amino ketone from Lupasol G100 (commercially available from BASF with a content of 50 % water, 50 % Lupasol G100 (Mw. 5000)) and ⁇ -Damascone (or ⁇ -Damascone) was prepared using any one of these three different procedures described as follows:
• Lupasol G35 or Lupasol HF is used instead of Lupasol G100.
• the obtained mixture (so-called particle), as herein before described, is pour onto the coating material and agglomerated it in a Braun Mixer. Care is taken that the temperature during the mixing and/or coating step does not substantially exceed the melting point of the carrier material. For example, 130g of a mixture containing the citric acid salt of the amine reaction product and 39g of PEG 4000 is poured at 60°C into a Braun Mixer containing 50g of carbonate. The mixing of the ingredients is carried out for about 5 minutes. Care is also taken that the temperature during the coating does not exceed 60°C.
